AITech International Inc of Fremont, California, says its MultiPro CTV external encoder is now available. Users can transfer their personal computer video images to a VCR at a much lower cost than alternative methods, it says. It supports both PC and Macintosh environments and features include freeze frame, overscan/underscan control and on-screen vertical adjustment. It has a built-in RF modulator and is compatible with AITech’s desktop video products and Windows 3. Applications include video recording; displaying presentations, training and educational programs, and PC games on TV; and big-screen computing. NTSC and PAL versions will be available for $400. The NTSC version will begin in March and the PAL version in the second quarter.
